This high quality Animation Disc is manufactured from tough and durable black Plexiglas and features a clear plate glass drawing surface that is resistant to scratching and easy replaceable. The glass is held in place with clips. Beneath the glass and permanently attached to the disc are two layers of translucent white Plexiglas to help reduce glare from the light source. Each pegbar features 5 brass Acme registration pegs. The three centre pegs are fixed and the outer pegs are "Flexipegs". Both pegbars are now slightly shorter to enable a full 360-degree rotation in most desktops.
